Headless Firefox has the same maturity as that of Headless Chrome for front-end test. Similar to Headless Chrome, with Firefox in headless mode we now get to enjoy browser tests without the visible UI components, executing the UI tests suite much faster.

When developing front-end applications, we've mentioned Headless Chrome as a better alternative to PhantomJS for front-end testing in a previous edition of the Radar. Now we suggest assessing Headless Firefox as a viable option in this area. In the same way as Headless Chrome, Firefox in a headless mode runs the browser without the visible UI components, executing the UI tests suite much faster.
